The Perfect Firm Pillow l
Size: Queen (1 Count), Color: Original White (Cooling)
It is everything it claims to be, cool, comfortable and strong. I got this for my husband first, he loves it and then got one for my son, he uses it to support his knees and has been sleeping much better since then.
They both needed a firm pillow that is not super soft, firm but not achy.
Finally found the perfect one.

A product that will make a difference!
Color: White, Size: King (Pack of 2)
These king-size pillows are incredibly comfortable and supportive. They are soft enough to feel luxurious, yet they provide great support for my head and neck throughout the night. The king size is perfect for a larger bed and gives the bed a full, hotel-like appearance. The pillows keep their shape well and fluff up nicely after use. I've been sleeping much better since getting them and would definitely recommend them to anyone looking for quality, comfortable pillows.

Soft...but fluffy and tall
Color: White, Size: Standard (Pack of 2)
I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.
